Description

Description: TECHNICAL FIELD The present invention relates to a manual fire extinguisher in which a person holds a nozzle and discharges a fire extinguishing agent toward a fire source, and in particular, the nozzle is attached to a main body of the fire extinguisher. The present invention relates to a fire extinguisher in which an internal structure of a starting portion provided as a structure for starting discharge of a fire extinguishing agent at the time of a fire extinguishing operation is improved.

[Conventional technology]

Conventionally, various manual fire extinguishers or fire extinguishers have been proposed and implemented.

For example, in Japanese Utility Model Laid-Open Publication No. 64-20867, a fire extinguisher discharge nozzle is always attached to a valve opening mechanism of a fire extinguisher container to keep it in a non-starting state. There is disclosed a fire extinguisher having a structure in which a fire extinguisher is activated.

[Problems to be solved by the invention]

However, in this type of fire extinguisher, if the nozzle is inserted and removed in a predetermined direction, the operation can be easily performed easily. That is, extra pull-out force and insertion force are required. In fire emergencies, fire extinguisher operators generally have no mental margin,
There is a possibility that the nozzle cannot be pierced in an accurate direction and cannot be used for fire fighting.

On the other hand, in the above-mentioned conventional fire extinguisher, after the nozzle is pierced and used for fire extinguishing activities, the nozzle can be mounted again to close the valve. If the user forgets to replace the fire, there is a problem that the fire is no longer useful for firefighting.

In view of the above problems, the present invention provides a fire extinguisher with extremely good operational performance that can reliably and easily execute the hole removal of a nozzle even in a situation where an operator lacks stability due to a fire. To provide.

On the contrary, another object of the present invention is to provide a fire extinguisher which has a structure in which the nozzle cannot be easily re-attached once the nozzle has been pierced, and which has a structure which actively promotes the replacement of the fire extinguishing agent or the replacement of the fire extinguishing container.

[Means for solving the problem]

The present invention relates to a manual fire extinguishing device, in which the extinguishing agent container is automatically opened when the extinguishing agent discharge nozzle is pulled out from the starting portion as an internal structure of the starting portion, thereby enabling the extinguishing agent to be released and the extinguishing agent to be discharged. A simple pivoting means that the fire extinguisher discharge nozzle can not be returned to the start-up area and the fire extinguisher can be returned to service unless the fire extinguishing agent is refilled or the fire extinguishing agent container is replaced with a new one. Provide a metal member,
In addition, a nozzle guide is provided to enable the operator to reliably and easily extract the fire extinguishing agent discharge nozzle during fire extinguishing work with a high degree of urgency, so that the fire extinguishing function of the fire extinguisher is always guaranteed and operability is improved.

FIG. 3 is an enlarged partial cross-sectional view illustrating a normal state in which a fire extinguishing agent discharge nozzle of the nozzle device is mounted in a guide hole formed in a nozzle guide of a starting unit that starts opening of the fire extinguishing agent container, FIG. 4 is a similar cross-sectional view showing the internal state of the activation unit when the nozzle is removed from the activation unit.

Now, in the present embodiment, an explanation will be given taking a pressure accumulation type fire extinguisher as an example, but it goes without saying that the present invention is equally applicable to a pressurized type fire extinguisher.

In FIG. 1, a fire extinguisher 1 of a fire extinguisher has a fire extinguisher container 2 in which a fire extinguisher (not shown) is hermetically filled while receiving the pressure of a compressed gas. A valve body 4 is attached to the upper part of the container opening 3 of the fire extinguisher container 2. An outlet 5 is formed in the valve body 4, and a tip of a hose 6 connected to the outlet 5 is connected to a nozzle device 7. A valve stem 9 projecting from the upper end of the valve body 4 (FIG. 3, FIG.
(Fig.) Is opened downward when pressed down as necessary. The outer casing 10 that integrally houses the fire extinguisher 1, the hose 6, the valve body 4, and the starting unit 8 has a hose 6.
A door 11 is provided so that the door can be easily taken out. The pedestal 20 on which the hose 6 is loaded is configured to lift the hose 6 so as to be at the same height as the lower end of the door 11. FIG. 2 shows a state where the door 11 of the outer casing 10 is opened.

Next, the configuration of the activation unit 8 will be described in more detail with reference to FIG. The valve stem 9 of the valve body 4 is provided so as to protrude toward the bottom of the actuating portion.
Located on the lower side of 12. The activation lever 12 has a hole 12a into which a pin 13a provided as a tip member of a safety plug 13 which is sealed at an upper end by a sealing seal (not shown) and which is normally maintained in a sealed state is fitted. At this time, since the pin 13a of the safety plug 13 is inserted through the safety plug guide 14, the starting lever 12 is mechanically fixed at a fixed upper limit position (the position shown in FIG. 3). It has a configuration in which it has one end 15a that engages with the activation lever 12, presses the activation lever 12 downward, and is stopped and held at the upper limit position despite the spring force of the activation spring 15 that biases it. I have. Also, the starting lever 12 and the nozzle at the tip of the nozzle device 7
A movable lever holder 16 is interposed between the lever lever 71 and the lever lever 71. The starting portion 8 has a guide hole 17 formed in a side surface portion thereof so that the nozzle 71 of the nozzle device 7 can be inserted into the starting portion 8 from outside.
The nozzle guide 18 is provided, and the provision of the nozzle guide 18 uniquely determines and guides the direction in which the nozzle device 7 is removed and the direction in which the nozzle device 7 is inserted. In normal times, that is, the fire extinguishing agent container 2 is filled with the fire extinguishing agent, the nozzle device 7 is mounted in the starting portion 8, and the safety pin 13 is inserted into the hole 12 a of the starting portion 8, and the starting lever 12
Is stopped, the nozzle at the tip of the nozzle device 7
A nozzle 71 is inserted into a guide hole 17 through a nozzle guide 18. The tip of the nozzle 71 pushes up a lever holder 16, and the push-up and the activation lever 12 of the safety plug 13 are performed.
The starting lever 12 is stably held at the upper limit position shown in FIG. The nozzle device 7 has a nozzle tip 71 and a nozzle lever 72. When in use, the hose 6 is pulled out, the nozzle 71 is directed to a fire source, and the fire extinguishing agent is ejected when the operator grips the nozzle lever 72 with a hand. It is configured to be performed. Here, the starting lever 12 and the lever holder 16 are both provided as inexpensive metal fittings manufactured by bending a sheet metal material. In particular, the lever holder 16 provided according to the present invention is shown in FIG. As shown in a front view and a side view in FIG. 6, a metal member having a simple U-shaped cross section having a through hole 16a for a pivot pin is provided around the pin fixed to the main body member 8a of the starting portion 8. And a position for closing a guide hole 17 in a nozzle guide 18 shown in FIG. 4, which will be described later. It is mounted so that it can be displaced between. On the other hand, the starting unit 8
Is attached to a part of the main body 8a, and in normal times the starting lever 12 is located at the upper limit position,
A micro switch in which the contacts are physically touched (this state is turned off) and the contacts are not contacted (the state is turned on) as the starting lever 12 pivots downward at startup.
19 are provided. In other words, this microswitch 19
Sends a signal indicating activation to the outside at the time of activation. In the configuration of the above-described embodiment, the starting spring
Although 15 is a coil-shaped spring, any other leaf spring or the like may be used as long as it has an action of applying a biasing action to the activation lever 12.

Next, the operation of the fire extinguisher according to this embodiment having the above-described configuration will be described.

After the fire extinguisher 12 of the present fire extinguisher is installed at a predetermined position, the seal is cut off and the safety plug 13 is removed. At this time, the lever holder 16 and the tip nozzle 71 of the nozzle device 7 are still in the nozzle guide 18.
The activation lever 12 does not operate because it is inserted into the guide hole 17 of the first embodiment. Therefore, the micro switch 19 is off. The operator holds the nozzle device 7 and sets the guide hole 17 in advance.
The nozzle tip portion 71 attached to the nozzle is pulled out according to the guide of the nozzle guide 18. Then, the starting lever 12 locked by the nozzle 71 is pivoted downward around the pin 12b by the pressing force of the starting spring 15, and is pressed down,
It is displaced toward the valve opening position of the valve body 4 shown in FIG. Thus, the starting lever 12 pushes the compressed gas (not shown) inside the fire extinguishing agent container 2 and the valve rod 9 pushed upward by the spring 91 inside the valve body 4 to the internal pressure of the compressed gas inside the fire extinguishing container 2 and the spring. Press down against the spring force of 91. The valve opening (not shown) of the fire extinguishing agent container 2 is opened by the pressing action of the starting lever 12. In this state, the fire extinguishing agent has not yet been ejected from the fire extinguishing agent container 2, but the microswitch 19 is turned on and sends a start signal to the outside. Since a fire is an emergency that is urgent and urgent, it is reported by the initial operation of fire fighting. The lever presser 16 has come to a position (FIG. 4) at which the guide hole 17 is closed by the activation lever 12, and if the lever presser 16 is pivoted to this closed position, the nozzle 7 is easily remounted. It is not possible. Next, the operator carries the currently held nozzle device 7 toward the fire source. That is, when the nozzle 7 is pulled out from the door 11 of the outer casing 10, the door 11 previously hooked is released from the hook, and the door is urged in the opening direction by the spring force of the spring (not shown). In addition, a hose is placed on the pedestal 20, and the lowermost hose is placed at the same height as the door 11, so that the hose 6 can be smoothly taken out. (If there is a difference between the housing and the lower end of the door, the hose may be hung.) As a result, since the hose 6 is connected to the nozzle device 7, the nozzle device 7 can be pulled out together with the hose 6, and only the length of the hose 6 can be obtained. Approaching a fire at a distance,
Can respond. Even in the case of a fire near the fire extinguisher, it is only necessary to carry the hose a necessary distance, and the hose 6 is used as a
Even if it is still stored, the fire extinguisher can be sprayed because it is not stored in a folded state.

Next, the operator directs the tip nozzle 71 of the nozzle device 7 directly to the fire source, and operates the nozzle lever 72 by grasping it. As a result, the fire extinguishing agent passage in the nozzle device 7 is opened, and the fire extinguishing agent in the fire extinguishing agent container 2 passes through the coiled hose 6 by the pressure of the compressed gas via the valve that is already open. From the nozzle device 7. In other words, in response to a fire within the distance of the coiled hose 6, the operator only needs to grip and operate the nozzle device 7 with one hand independently of the other members, and the fire extinguishing agent is spontaneously sprayed toward the fire source. The fire can be extinguished at the beginning. In the present embodiment, the starting portion of the pressure-accumulation fire extinguisher has been described.

Further, according to the present invention, once the nozzle 71 at the tip of the nozzle device 7 is pulled out from the main body 8a of the activation unit 8 and the fire extinguishing agent is discharged, as described above, the holding lever 16 is moved to the nozzle guide. The 18 guide holes 17 are closed inside. In addition, the closed state is determined by removing the starting portion 8 from the fire extinguisher 1 and filling the extinguishing agent container 2 with the extinguishing agent, or replacing the extinguishing agent container 2 itself with a new one, for example, by setting the starting lever 12 inside the starting portion 8.
Unless after the operation of pushing up to the upper limit position, the starting unit 8
The nozzle 71 at the tip of the nozzle device 7 cannot be mounted in the main body 8a. Therefore, the nozzle unit 7 is activated by the activation unit 8
The state that is fitted guarantees that the fire extinguisher is always ready for use.

(Effect)

As is apparent from the above description, the fire extinguisher according to the present invention holds the starting lever at a certain immobility upper limit position by the safety stopper and the lever retainer accompanying the mounting of the nozzle. It is stable in the open state. In addition, since the nozzle guide is provided in the starting part, the direction of the hole of the nozzle becomes constant, and in the event of an emergency such as a fire, the ordinary operator can easily perform the extraction operation even in a swaying state such as panic. obtain. Further, a start signal can be sent to the outside as the nozzle of the nozzle device is withdrawn from the start unit, and there is an effect that a countermeasure following the operation of the fire extinguisher can be quickly performed. Moreover, after the nozzle of the fire extinguisher is once pierced, the nozzle cannot be easily reinserted, so that the fire extinguishing agent is not installed with the container empty.
